ROTARY DRILLING 0R SOWING- MACHINE.

Patented May 20, 1919.

Application filed December 27, 1917. Serial No. 209,150.

To all whom it may concern:

Be it known that I, CYPRIEN EDOUARD PAUL JULLEN, a citizen of the FrenchRepublic, and residing in Paris, France, 1 Avenue de lObservatoire,engineer, have invented certain new and useful Improvements in andRelating to Rotary Drilling or Sowing Machines, of which the followingis a complete specification.

This invention relates to a rotary drilling or sowing machine for allkinds of seed or manure, in continuous or discontinuous lines, withrational compression of the seed. It is essentially characterized by acircular rim in the form of a disk or wheel provided with pins, the saidwheel rotating, while rolling along the ground, about an axle whichsupports, by means of a frame, a seed or -manure hopper, communicating,by means of a distributor actuated by the pins, with a detachable tubewhich conveys the seed either to the front or to the back of the rim.

In the accompanying drawing, which represents by way of example oneconstructional form of the invention Figure-1 is a front elevation of agroup of two drills or sowing machines or elements coupled together.

Fig. 2 is a side elevation of Fig. 1, showing the triangular supportingframe carrying at its forward end a draw bar bearing upon afore-carriage wheel.

Fig. 3 is a longitudinal section on a larger scale of the arrangementfor regulating the How of seed.

Fig. 4 is a cross section thereof, through 4-4 of Fig. 3.

Fig. 5 is a cross section of a modification of Fig. 4.

In Fig. 1 the machine comprises a wheel or disk 1 rolling along theground and rotating about an axle 2. This disk is provided with pins 3.The axle 2 is fixed to the base of triangle frame 4:, which is connectedat one base angle with a fore carriage, and which carries thedistributing hopper 5, at the top or apex angle (see Fig. 2) 1 and uponwhich hopper may be located the fulcrum 6 of a lever arm 7 placed so asto oppose the pins 3. The frame 4 is supported by slotted sectors on theaxles of the traction The bottom of the hopper 5 is pierced with anopening 8 in the shape of a truncated cone corresponding to a cav ity 9,also in the shape of a truncated cone, formed in a sliding member 10which is actuated by the rod 11 connected to the lever arm the smallerends of the two frusto-truncated conical openings 8 and 9 being incontact with one another that is to say, being opposed to one another insuch a way as to be reversely inverted. A coil spring 12 serves toreturn the sliding member. One of the walls of the slide-valve box orcasing is pierced with an opening 13 about which is fitted a detachablenozzle 14.

The method of working is as follows The wheel 1, rolling along theground by being pulled or pushed, in rotating about its axle 2, actuatesby means of the pins 3 the lever arms 7 in such a way that the seedscoming from the hopper 5 through the outlet 8 into the frusto-truncatedconical cell 9, fall into the aperture 13 of the detachable nozzle 14.which conveys them to the ground either in front of or behind the wheel.

A drilling or sowing machine element forming a complete whole maycomprise a disk provided with its hopper carried by the axle of thedisk, together with the mechanism for operating the regulating slidevalve. Several drill elements may be coupledv together, in groups of twoelements for instance on the same axle and these groups may be yoked invarious numbers to the same draw bar, bearing or not on a fore-carriage.

The sowing wheel may be preceded by a rigid or resilient plow share orcolter, opening a furrow as it passes. It may be followed by animplement returning the loose earth over the seed. It may also beprovided with an automatic cleaner.

The pins hereinbefore referred to may be detachable, in such a way as torender it possible to vary their number for the purpose of varying atthe same time the spacing of the seeds. The lever that operates theregulating device may furthermore be moved away from the pegs, so as tosuspend at will the operation of the regulating slide valve.

The plate containing the frusto-truncated conical cell of the regulatingslide is of variable thickness according to the seeds and the quantitiesto be sown. The slide may moreover be double or treble acting,- that isto say, it may be provided with several cells permitting of thesimultaneous distribution of seeds or manures, the feed being efiectedby means of several hoppers coupled together.

As plainly shown in Figs. 1 and '2 the frame 4 which carries axle 2 issupported by slotted sectors on the axles of the traction wheels, thesesectors being maintained on the axles by means of nuts, so that it ispossible by varying the position of the traction Wheels due to the slotsin the sectors, to vary the weight supported by the wheels 1, and inconsequence the compression of the seed in the furrow.

The supporting wheels illustrated in the drawing may be omitted. Thepivot 6 of the lever arm 7 may, in some cases, be located on the framee.

WVhat I claim is:

1. A rotary seed drilling and sowing machine comprising in combination aframe, an axle supported therein, a circular disk revolubly mounted onsaid axle, a circular series of pins projecting laterally from said diskadjacent its periphery, a hopper supported in said frame directly oversaid axle and above the periphery of said disk, distributing means inthe lower end of said a detachable and reversible tube communit eatingwith said distributing means, whereby seed may be conveyed to either thefront or rear of the rim of the aforesaid disk.

2. A device-as herein characterized in cluding in combination a pair oftraction wheels and'axles projecting inwardly therefrom, slotted sectorsadjustably supported on said axles, another axle supported at the lowerends of said sectors, disks revolubly mounted on the last mentionedaxles, triangular frames supported at their base on said axle, seedhoppers supported at the apex of said triangular frames in verticalalinement with'the axle last mentioned, and means actuated 'by therevolution of the disk to successively feed seed from the hoppers to thefront or rear of said disk.

In testimony whereof I have hereunto set my hand, at Paris, (France),this 30th day of November, 1917.
